Guess this as good a place to start a discussion!
 
Will be replacing all fuel lines on our JD 155C, B&S Intek V-Twin this Spring, tank to carb. Anyone using Tygon? Read some mixed reviews on Tygon. Some praise it while others mention shrinking, hardening, leaking in 2 years etc. (Not to mention price.) Minor concern is the sharp bend at the fuel tank inlet on the JD (possible kinking). 
 
I've used Tygon on all my 2 cycles with no issues to date but 4 cycle???
 
Thanks in advance for comments.
